Notes
-
All the measurements are averaged over one second
If a transformer is used for the voltage measurement, the harmonic voltage
-
measurements may be erroneous due to the filter behavior of the transformer.
The use of a high quality transformer will minimize the error.
(1) The range values have to be multiplied by the CT ratio (Irms - I1 - P - Q - S -
missing Q) and the PT ratio (Vrms - V1 - P - Q - S - missing Q).
(2) Displacement power factor or cos j : calculation based on the fundamental
value of the measurements. This value is used as the reference value by
Electricity Supplies Companies.
(3) Power factor: calculation based on the fundamental and harmonic values of
the measurements. The power factor is always lower than or equal to the
displacement power factor.
The Overview menu displays all measured items in a list.
